Here is a new fanfic with an OC and Jack! Hope you enjoy!

Pitch had fallen. The Guardians had once again saved the children of the world from fear and darkness. Now the Guardians had gone their separate ways. But there is one guardian who wasn't known to Jack Frost. The Greeks called her Persephone, but she prefers Daughter Springtime.

Jack's POV

Flying in the wind is my favorite thing to do now a days, since there's no war with Pitch. I spend my days doing what I've always done; just watching over the seven kids that helped us in the war, especially Jamie and Sophie. As I was flying over the town, I saw Jamie and his friends hanging out in the park. I decided to have a little fun.

I flew down and landed on a branch ten feet up and away from where they were sitting.

"Looks like winter started really early this year," Cupcake said. Jamie smiled.

"Jack must really want snow," Jamie replied and looked up at the sky and smiled. I smiled at that remark, "He still believes in me." It had been three years since Pitch had attacked and Jamie had still held to his belief in Jack Frost.

Silently, I creped to a branch just above the kids, and started to make a snowball. I held it over Pippa's head and dropped it. It shattered on her head and she cried out.

"Who threw that?!" Pippa yelled and made a snow ball threw it at Caleb. Then the war began. Jamie got out of the range of fire and looked franticly around. I smiled to myself; it had been a year and a half since I had started a snowball fight. Jamie caught eyes with me and smiled.

"Up there!" Jamie yelled and rest of the kids responded immediately. I saw snow balls and felt myself fall out of the tree, laughing. The kids mobbed me and we all tumbled into a huge heap.

"I can't believe you all still believe in me," I smiled as the kids tumbled off of me so they could look at me.

"DUH! Of course we do!" Jamie laughed and jumped on me again. I fell back again but this time, I hugged Jamie back. Jamie pulled back and kept on smiling like it was Christmas… well it was four days till Christmas.

"What are you doing here, Jack?" Sophie cried, now five years old. I smiled seeing how much they all had grown.

"Checkin' on you guys of course!" I smiled and hugged them one by one, starting with Sophie.

"Um, Jack…" Pippa said, shyly, "The Northern Lights aren't supposed to show up in Virginia." Fear stuck into my heart.

"I have to go," I said, hurrying to get up. Jamie looked at me with concern.

"What's wrong?" Jamie asked and the kids mumbled in agreement.

"Santa is calling a meeting of the Guardians, which is never good news; especially so close to Christmas." I said and Jamie nodded and told the kids that they should go to his house. They all gladly complied but I could still see that they didn't want to leave.

I flew up into the air and within ten minutes, I was at the North Pole. I flew in and everything was busy as usual, but there was an eerie feeling in the air.

"Jack!" Tooth called from behind me, and she flew into a hug. She ruffled her feathers and smiled at me. "I'm so glad you're here…," then she started looking me over, "Have you been starting snowball fights again? DID YOU VISIT THE KIDS? How's Sophie? Does she remember us? She was so young…" but I had cut her off there otherwise I would be standing there all day.

"Yes… yes… she's fine… and of course she does," I said, answering her questions. Don't get me wrong, I love Tooth, but like a mom. All she does is dote on me. Sometimes it can be annoying.

"That's good…," Tooth said, but trailed off as North, Bunnymund, and Sandy came into the main room, all of them looking grave.

"What's wrong?" I said not sure if I wanted to hear the answer. North looked at me and slightly smiled. Bunnymund didn't look to happy to see me, but I guess old scares fade slowly. Sandy tried to say, "Nice to see you," but what I saw was, "Ice two sea you". Man… Sandy was out of it today.

"Jack…," North said, in his heavy Russian accent, "So glad to see you."

"Yeah, mate," Bunnymund said, in his Aussie accent, "It's been getting' might crazy on our end, 'ay Sandy?" Sandman nodded his head grimly.

"What is it?" I asked. North looked like he was going to cry, along with Tooth's face. Bunnymund looked more angry than sad.

"Pitch is back…" Tooth said. I was taken aback. Pitch… back?

"But he can't be back," I said, trying to believe the words I was saying, "We just got rid of him." I had always known Pitch would come back, but never in Jamie's lifetime.

"Oh, he's back alright," North said, his voice rising in volume, "And with a greater vengeance than ever before. He has attacked the one place that he won't be forgiven for." North was now so angry, his face was a sickly shade of tomato red.

"Did he attack the pole? Where is he? I'll make him pay for attacking you four day before Christmas…" North put his hand up and I stopped talking instantly.

"He didn't attack the North Pole, Jack," North said. I was confused.

"Then were did he attack?" Tooth looked solemn at me. North still looked furious and Bunnymund still had a sour look on his face.

"Jack… it is easier if we show you," North said after a long silence. He pulled out a snow globe and whispered something to it and tossed it into the air. It opened a portal and we all climbed through it.

When we arrived on the other side, we were standing on a small cliff. A field of thousands of flowers stretched out in every direction for almost ever. Hazy mountains could be seen in the distance. I looked at North, confused.

"This is the place I told you about," North said, "Welcome to-…" but he stopped talking when another voice continued his sentence.

"…the Haven of Life." I turned around and saw a red haired girl about my age with a flowing green dress on. She smiled only slightly when my mouth dropped.

"Welcome, Jack Frost. We meet at last," the girl said, but I was still confused. Who was she? Why was I here? Why would Pitch attack flowers?

"Spring!" Tooth squealed and flew to hug the girl. The girl smiled and hugged Tooth, Sandy, Bunnymund, and North as if they were all old friends. I felt a little left out.

"Who are you? What is this place and why did Pitch attack flowers?" I asked in a blur, but the girl didn't look fazed by my explosion of questions.

"My name is Daughter Springtime, more commonly known by my Greek name of Persephone. This is the Haven of Life and the flowers hold more power than you ever could imagine," the girl, Daughter Springtime, said. I was still kind of confused but decided to let the matter past from my mind.

"So…," I said, "How can I help?" Daughter Springtime looked at me coolly.

"You," she said, "Cannot help me."
